The Applicant Guidebook (AG), drafted by ICANN, provides step-by-step the procedure for new gTLD applicants. It specifies what documents and information are required to apply, the financials and legal commitments of operating a new gTLD, and what to expect during the application and evaluation periods. You can access to the AG by clicking on the following link: https://newgtlds.icann.org/en/applicants/agb.
